Migration problem – Platinum SEO – Bad Home Title

I have a little problem with the “Platinum SEO” plugin – before installing this plugin I had installed “All in one SEO“, but I decided to change plugin to “Platinum SEO” so I made ​​the migration from the “All …” to “Platinum SEO“

After the migration, everything was ok except for one small, but quite problematic, “thing” – well the name – Home Title presents itself in this way:

< title >Seriale | Multi-Kino< /title >

and should be simply like this:

< title >Multi-Kino< /title >

In the plug-in settings I set homepage title to “Multi-Kino” , “also in the WP standard settings> General> Sites Title I set it to” Multi-Kino” but nothing change, when I cheak my site source code title still looks like “Seriale | Multi-Kino”
